To WHOM 1'1 MAY coNcERN: A j v i Be it known that I, FREDERICK On'rmnn, oi? Williamsburg, in the county of Kings, and State of New York,

have invented a certain new and improved Adr and Gas-Exhausting Attachment 'to Steam-Engine and other` Condcnsers, of which the following is a full',` clear, and exact description, reference: being' had to the accompanying drawing, forming part of this specification, and in' whiche- A Figure 1 represents a vertical section ot an apparatus constructedaccording to my improvement.

Figure 2 a plan of the same,` and 'i i Figure 3 an outside elevation of saidvapparatus connected, as illustrated by red lines, .with a surface coudenservand its pertaining devices. i v 4 Like letters indicate like parts throughout the several figures.

The object of my invention, which is more particularly designed to work in connection with a surface condenser, is to dispense with the use of an air-pump for extracting the air and gases from the chamber or spaces into which the steam to be condensed passes, and, in thus dispensing with an air-pump, to avoid not only the cost of such device and its maintenance 'in vrorking order, but the liability to derangement and failure ineidental topall such conti'ivanees, and to economizeand reduce that consumption of fuel and expense which the working of an air-pump, to clear the condenser, invariably entails. l

Having thus specified the object sought tolbe attained, the nature of my invention consists in a combina tion with the outboard delivery of the condenser, through'i'vhicl the water used to condense the steam is cir'- culatcd, of a novel arrangement of siphonicpipe or tube, operating to produce a Torricellian vacuum, and

inner pipe for extraction of p the heated air and gasesifrom the steam-condensing spaces or chamber of the con-A denser. Aud said invention further consists,'in such a combination, in giving to the pipewhich is used for extracting the heated air and gases from the steam-condensing spaces or chamber of the condenser, an adjustable character for operation, in connection with' a tapering construction ofA the outer siphonie pipe or tube, to control-or regulate the outflow of water through the latter. A

Referring to the accompanying drawing', A represents the outboard delivery of the condenser, which I make of reservoir form, and, when practicable, arrange at about thirty-three (33) feet' above the level of its outflow, that may here be supposed to be into a river or stream, B, with which -the communication-is .established b y a Pipe, C, 0f tapering or contracted -form, at or near its vbottonnas shown at b. This pipe C is in constantcommunication, through its outboard delivery-chamber A, with the condenser, and a continuous circulation or passage of water kept up between or through it and the several tubes or water-spaces of the condenser by a rotary or other circulating pump, drawing water from below and discharging into' the condenser above. When water under pressure is otherwiseobtainable, of course the pump may be dispensed with, but'in caseof using a circulating pump I prefer tomake at least one of'the injection deliveries from said pump furnish a head or pressure more or less above the level of; the condenser for the purpose of more perfectly filling the water-spaces of thecondenser to the exclusion ofiair, but such altitude ofv the injection waterA need add but little to the labor of working the circulating pump, as a siphonic action or counterbalance is established' to or of the main lift by the action of the descending column in the pipe O, which, exhausting the air, in the con* denser, opeiates asa vacuum on the column being raised by the pump. In this way the water may be said to circulate n vacuo through the'eon'denser. Connected with the condenser at its top, infree communication with the steam-condensing space or spaces thereof, is a pipe, D, of suitable diameterfo'r extraction of the air and gases, -the water formed by condensation of the steam being separately drawn oft by a lower pipe through a feed-pump and returned to the boiler. The pipe D, which Vis represented as of bent or angular form, isarranged, by a suitable connection or extension', to pass through theA outboard deliverywhamber A, said connection or extension D being further passc'd'downwards within the pipe C, which forms a surrounding jacket to it, having an intervening annular space. The pipe D is made a fixture, and may be supported or held by a pillar, E, or otherwise,` but the extension branch D of'said pipe is .vertically adjustable to regulate the position of its lower end within the cone b of. the Siphon. pipe `C. This Aadjustment may be ,effected by a screw formation, e, of the extension pipe D at vits junction with the pipe D that ts through a stalling-box, d, therein,- and it fmay be through a guide, f, to steady the vertical movement of the extension pipe, which may further be steadied by a guide, g, below. F is a revolving screw-box or wheel, workinginvxed bearings in a frame, G, and receiving through it the screw formation c of the extension pipe D', so that by turning said screw-box to the right or left the extension pipe is raised or lowered, as circumstances may require.

On starting the apparatus the extensionpipe D is lowered by turning the screw-box F so as. to close or nearly close the conical outlet after the manner of o. valve, when the circulating pump is set in motion to fill the water-space or chambers of the condenser-,outboard delivery-chamber A, and siphon pipe C, ti-ll an overow is estublishedfrom the condenser through a weighted or other vulve provided for the purpose. This insures all air being discharged fromv the water space of the condenser, so that the .after-circulation is kept up in vacuo, as it were. A The extension pipe D is then raised to establish a ow through vthe cone b, and the overflow-valve ofthe condenser closed, when, by a circulation of water being established by the pump through the watertubes and -pipes or spaces of the condenser, outboard delivery A, and flown. through the siphon pipe C, the water descending in the latter draws upon the condenser to establish an equilibrium with the lift or approximotion thereto, or to suck uponI the condenser, as it were, and at the sometime to draw oi air and gases by the pipe D and .its extension D', entering,jiu 4the working ofthe engine oir-otherwise, the steunt-condensing space or spaces ofthe condenser, and discharging it with-the outow through the cone b into and through the stream or water in which the lower end ofthe Siphon pipe C is placed. By this Ineens a. more or less perfect vacuum is established throughY the pipe D and its extension D in the condenser, and the same maintained without the aid of an air-pump.A The outowthrough Athe pipe G may be regulated to suit requirements` by simply raising or lowering the extension pipe D so as to more or less contract the'outlet through the cone I), increasing,-

for instance, the discharge of water in summer; when the atmospheric temperature i'srhigh, andzdiminishing it in winter, when the temperature is lower, and a less rapid circulation of water through the condenser necessary. In some eases this adjustahility or valvular action of the cxtensionpipe D may be dispensed with und a. fixed outflow through the pipe C be established' What I claim es iny invention, and desire to secure by Letters Patent, is

1. The outer siphonic pipe through which the water from the condenserilows for extracting the air 'and gases 'from the steum-condensing` spaces through `a'pipe or pipes communicating therewith, essentially as set forth.

2. The combinutionof the water-circulating or siphonie pipo C with the pipe D or Aits extension D', made adjustable so as to regulate the outflow through the pipe C, for operation in connection with the condenser,

substantially as specified.
